Envirosense™ Power Vent 90% Efficient Gas Water Heater

Brand :
John Wood

The Envirosense™ Power Vent is an ENERGY STAR® qualified, 50-gallon, 76,000 BTU gas water heater, equipped with a fully submerged, spiral-shaped condensing heat exchanger. This design provides much greater heat transfer surface than a standard straight flue tube, resulting in 90% thermal efficiency and higher hot water output than standard 78% efficient water heaters. With a 22” diameter, Envirosense™ Power Vent can be installed in less space than a 75-gallon unit and delivers greater recovery and lower operating costs. The Envirosense™ Power Vent is so advanced, it can deliver endless hot water shower after shower... at a continuous flow of over 3 gallons per minute.*

  • POWER VENT DESIGN FOR INSTALLATION VERSATILITY
    - Modular blower, with 120V, 60Hz electrical system (5 amps or less), 6-foot cord with standard 3-prong connector
    - Combined horizontal and vertical vent runs terminating through outside wall, using ULC S636 PVC, CPVC or polypropylene pipe as follows:
      - 2 ? pipe allows vent runs up to 25 equivalent feet
      - 3 ? pipe allows vent runs up to 65 equivalent feet
      - 4 ? pipe allows vent runs up to 120 equivalent feet
    - Supplied with PVC pipe and elbows to connect heat exchanger outlet to blower, including condensate elbow and drain, and ULC S636 PVC Vent Attenuation Assembly (VAA)

    SIDE-MOUNTED TAPS FOR RECIRCULATING SYSTEMS
    - Hot and cold “side taps” allow the Envirosense ™ Power Vent to be used for “combination” systems for water heating plus space heating, radiant floor heating or other applications requiring a recirculating hot water loop
    - Plugs for recirculating taps are shipped with water heater

  • INTELLI-VENT GAS CONTROL WITH SILICON NITRIDE HOT SURFACE IGNITER
    - Premium-grade hot surface igniter eliminates standing pilot
    - Electronic circuitry provides superior system diagnostic capabilities plus extremely precise temperature control

    COMMERCIAL-GRADE GLASS LINING WITH TWO MAGNESIUM ANODE RODS
    - Superior protection against tank corrosion
    - Glass lining protects all “water side” tank surfaces plus inside of internal heat exchanger exposed to condensate

    DIFFUSER DIP TUBE - Helps reduce lime and sediment buildup, maximize hot water output
    - Cross-link polymer withstands long-term exposure to temperatures up to 400°F

    SIX-YEAR LIMITED PARTS AND TANK WARRANTY
    - Consult written warranty shipped with water heater or contact
    - GSW for complete warranty information

    AVAILABLE IN NATURAL GAS ONLY
    - * 3.07 GPM continuous flow, based on 65ºF/18°C inlet water temperature and 110ºF/43°C outlet water temperature.
